The Grandmother in the Siheyuan

Chapter 321 Following
A family of three was walking on the beach. Liu Hua held his wife's hand and held his daughter with the other hand. His wife was a little embarrassed. It was a bit awkward for an old couple to hold hands.

Liu Hua, however, was not shy at all. His thought was that this was my wife and I could hold her hand however I wanted.

The daughter-in-law said with a hint of regret: "What a pity, Guodong didn't come."

"Why worry about that?" Liu Hua said nonchalantly, "The eldest is already an adult. If he wants to come to the beach to play in the future, let him bring his girlfriend. What's the point of him being with his parents?"

"Does the boss have a partner?"

Liu Hua shook his head: "How should I know?"

"Aren't you in the same school as the boss? Go ask around."

Liu Hua shook his head like a rattle: "I'm a professor in the semiconductor department of Huaqing University and a graduate tutor. It's okay. Going to find out if my own son has a girlfriend is not worth my reputation."

"Can't you pay more attention to your son's lifelong event?"

Liu Hua shook his head: "No, if he wants to find a wife, he has to work hard on his own. I can't help him at all."

"I didn't ask you to help him, but you can help me find out."

Liu Hua still shook his head: "This is the child's own privacy. If he is dating someone and doesn't want to tell you, it means he feels that the time is not right. If we rashly ask about it, the child will feel uncomfortable."

After strolling on the beach, the family went to a guesthouse by the sea, where they ordered Tsingtao draft beer and fresh seafood, which everyone ate to their heart's content.

"I have to go to work tomorrow, so I can't hang out with you two anymore." Liu Hua sighed and said, "You can walk around the base if you have nothing to do. If you want to go out, call the guard and tell him. They will send security personnel to follow you."

"It doesn't matter. I've been here for so many years. Isn't it always like this? Once I'm immersed in scientific research, I don't care about anything else. I'm used to it."

Liu Hua said guiltily: "Now that you mention it, I feel a little sorry for you. We have been married for so many years, and I have always let you take care of things at home. I have never taken you out to play. This time I took advantage of the opportunity of work."

"It doesn't matter. Our generation is destined to work hard to build the country for our children and grandchildren."

The next day, Liu Hua threw himself into the intense work. The submarine base sent more than a dozen experts to study the structure of the silencing tiles with Liu Hua.

Based on the limited information we collected from abroad, they quickly determined how to design our own sound-absorbing tile structure.

However, they did not satisfy the foreigners' design. Although they have their reasons, it does not mean that we cannot surpass them.

The superiors also dispatched two experts in acoustics to cooperate in the design of sound-absorbing tiles. For a month, they designed more than a dozen models and finally decided on a model that was different from Western designs, but its sound-absorbing efficiency was greatly increased.

After finalizing the model, they submitted an application and decided to go into mass production. The application was submitted on the first day, and they received a reply and it was approved on the second day.

The relevant factories worked around the clock to produce the anechoic tiles. There happened to be a submarine under maintenance in the port, so they used the submarine as a model and began to lay the anechoic tiles. It is well known how efficient we are. In less than two months, the anechoic tiles were laid.

We started sea trials right after that, and the results were very ideal, at least our sonar could no longer detect it.

Taking advantage of this gap, Liu Hua started to study pump-jet technology with experts from the submarine base. Foreign countries already have shaft pump-jet technology, but Liu Hua and his team are targeting shaftless pump-jet technology.

When Liu Hua proposed his large model, the experts felt their scalps tingling. This design was too impressive. Even after only rough calculations this year, they already felt that this design was very likely to be successful.

Just when Liu Hua and his team were designing the pump-jet technology, submarines equipped with sound-absorbing tiles were sailing on the sea.

It was just a coincidence that the Seventh Fleet of the United States has been hanging around us, and somehow the two courses intersected.

When the submarine and the aircraft carrier met, our soldiers were brave and careful, and they simply changed course and followed the American aircraft carrier.

After circling around us, the American aircraft carrier headed for Sasebo with satisfaction. Not long after it started, the radar soldier reported that an unidentified ship was found twelve nautical miles to their port side, with an extremely small reflective area.

The aircraft carrier quickly sent a frigate to check it out. When they got close, they finally discovered that it was actually a submarine of the Flower Planting Family.

When the aircraft carrier commander received the report, his head was buzzing. He absolutely could not believe that the submarine had just arrived here.

You know, as a powerful American aircraft carrier fleet during the heyday of national strength, the protection circle of their aircraft carriers is very large. Now that the submarine was discovered at twelve nautical miles, this is a serious matter.

The supreme commander quickly sought answers from the sonar operators of the surrounding frigates, submarines, and destroyers, such as when did the submarine encounter the aircraft carrier, how did it break in, and whether it followed it all the way.

No clear answer was received. To be precise, the sonar of the aircraft carrier fleet did not detect the submarine.

The commander of the aircraft carrier was even more worried. At a command, the Seventh Fleet headed towards Sasebo at full speed without any hesitation.

After returning to the base, the situation was immediately reported to the country. The generals in the country also felt overwhelmed. Now it was just an ordinary attack-type anti-submarine submarine. If it was a strategic nuclear submarine, how should they deal with it?

So he quickly ordered to find out the reason immediately, and ordered all high-tech laboratories and companies to update the sonar immediately. They couldn't wait until the flower-growing country's submarine reached their west coast before responding.

So Congress voted to allocate a large sum of money. After layers of exploitation, Commissioner Smith made a lot of money from it, and then they used the meager salary to order scientists lured from various countries to help them research new sonar.

When Liu Hua and his colleagues were still drawing the blueprints of the shaftless pump-thrust submarine, the submarine came back with good news. They followed the American aircraft carrier for a long time, and the Americans seemed to be unaware of it.

Coincidentally, we have collected information in our country that the U.S. Congress has allocated funds for the research of new sonar.

These two things prove that the Americans really did not discover our submarines equipped with silencing tiles. Of course, this is the first time that the Americans did not discover the unexpected effect of our silencing tiles, and they will definitely be on guard in the future.
